Compact Scheduling for Deallocated Operations and Selected Orders The following graphic explains, in the form of an example, how the system executes

Compact Scheduling for Deallocated Operations and Selected Orders
Orders A, B and C each contain the scheduled operations 10, 20 and a deallocated operation 30. The end-start relationships between operations 10 and 20, and between operations 20 and 30 are defined with a minimum interval of 0.
When you reschedule the scheduled operation A10, order A is the order selected for scheduling. The system, therefore, schedules the whole of order A compactly; that is, it tries to do the following:
Shift the scheduled operation A20 as close as possible to operation A10, taking into account the minimum interval
Shift the deallocated operation A30 as close as possible to operation A20, taking into account the minimum interval
As a result of rescheduling A10, the scheduled operation B10 from order B is affected, for example, because the planning mode
Insert operation
is set, and B10 therefore has to be shifted. Due to the fact that order B is not a selected order for scheduling, the system only schedules the deallocated operation B30 for this order compactly; that is, it tries to shift the deallocated operation B30 up to the scheduled order B20.
Order C is not affected by rescheduling operation A10. Therefore, the deallocated operation C30 is not scheduled compactly; that is, it is not shifted towards operation C20.
